Product Introduction

Overview

The TL16C552FNR, produced by Texas Instruments, is an enhanced dual-channel version of the popular TL16C550 asynchronous communications element (ACE). This device serves two serial input/output interfaces simultaneously in microcomputer or microprocessor-based systems. It performs serial-to-parallel conversion on data characters received from peripheral devices or modems and parallel-to-serial conversion on data characters transmitted by the CPU. The TL16C552FNR is designed to be IBM PC/AT compatible and provides a fully bidirectional parallel data port that supports the parallel Centronics-type printer, making it a versatile component for various communication needs.
